What you’ll need before you begin

• A UniFi Dream Machine or Dream Machine Pro on a supported firmware version
• An active VPN service that supports gateway/remote VPN connections OpenVPN, WireGuard, or IPSec
• A computer or mobile device to access the UniFi Network app
• Basic networking knowledge IP addresses, DNS, and routing concepts

Option 1: VPN Client via IPSec ENTERPRISE/PROTOCOL-BASED on UDM
IPSec is a common choice for enterprise-grade VPNs and many providers support it. The UDM can act as an IPSec client, but you’ll typically use a site-to-site style tunnel or client-to-site with static routes. This method works well if your VPN provider supports IPSec IKEv2 with certificate or pre-shared key.

Step-by-step

1. In your VPN provider’s portal, generate or download your IPSec credentials PSK, username/password or certificate, and server address.
2. Open the UniFi Network app, go to Settings > Routing & Firewall > VPN > IPSec Client.
3. Create a new IPSec client entry:
   • Server address: VPN server DNS or IP
   • Remote identifier and local identifier: as required by your provider
   • PSK or certificate: input as provided
   • DNS settings: specify your preferred DNS optional
   • Phase 1/Phase 2 settings: match provider’s recommendations
4. Save and apply. The UDM will attempt to establish the tunnel.
5. Verify the tunnel status in the VPN section and check a device on your network for IP change your external IP should reflect the VPN exit.
6. Test connectivity: access geo-restricted content or run a DNS leak test to ensure traffic routes through the VPN.

Pros

• Stable and widely compatible
• Strong security with certificate-based or PSK

Cons

• Can be more complex to configure
• May require provider-specific adjustments for DNS and routing

Option 2: VPN Client via OpenVPN on UDM
OpenVPN has broad compatibility and is commonly used for VPN clients on a router. The UniFi Dream Machine supports OpenVPN clients but with some setup quirks depending on firmware. This is a solid, reliable choice if your VPN provider offers an OpenVPN config file.

Step-by-step

1. Get the OpenVPN config file from your VPN provider usually a .ovpn file and a CA certificate. You may also get separate certs and keys.
2. In UniFi Network app, go to Settings > VPN > OpenVPN Client.
3. Create a new OpenVPN client:
   • Server address: the OpenVPN server host
   • Port and protocol: as provided usually 1194 UDP
   • Certificate/key: upload the client certificate, key, and CA if required
   • Username/password: if your provider uses them
   • Custom DNS: set if needed
4. Save and apply. The Dream Machine will connect to the OpenVPN server.
5. Confirm the tunnel status and perform a quick test: check external IP and run a leak test.
6. Optional: enable DNS routing through VPN to prevent leaks. If you want split tunneling later, you can adjust policies to only route specific devices or subnets.

Pros

• Great compatibility, straightforward if you have the .ovpn data
• Good performance with proper server selection

Cons

• Must manage config files and certificates carefully
• Some providers require additional tweaks for DNS routing

Option 3: VPN Client via WireGuard on UDM Recommended for speed
WireGuard is fast, modern, and simple to configure. If your VPN provider supports WireGuard, this is often the best balance of performance and security. The UniFi Dream Machine with the latest firmware supports a WireGuard client setup that’s straightforward.

Step-by-step

1. Check with your VPN provider for a WireGuard config file or the necessary peer information public keys, allowed IPs, endpoint, and preshared key if used.
2. In UniFi Network app, navigate to Settings > VPN > WireGuard Client.
3. Create a new WireGuard client:
   • Public key: from the VPN provider
   • Private key: generated or provided by the provider
   • Preshared key: if required
   • Allowed IPs: typically 0.0.0.0/0 to route all traffic or specific subnets if you want split tunneling
   • Endpoint: VPN server address
   • PersistentKeepalive: 25-60 seconds helps maintain NAT mappings
4. Save and apply. The UDM will establish the WireGuard tunnel.
5. Verify the connection status and test with an external IP check.
6. Optional: enforce DNS through VPN to avoid leaks, or set a local DNS resolver if you need to.

Pros

• Very fast, low overhead
• Simple key exchange, easier to audit

Cons

• Fewer providers support it compared to OpenVPN
• Some advanced features may require extra config

Option 4: Split Tunneling and DNS Considerations
If you want devices on your network to bypass the VPN for certain services, you can set up split tunneling. This is useful for streaming devices or local network access that doesn’t need VPN routing.

How to enable split tunneling

1. In your VPN client settings, adjust Allowed IPs or routing so only traffic to specific destinations goes through the VPN.
2. Alternatively, set per-device routing rules in UniFi: create firewall or network group rules to route specific subnets through the VPN tunnel.

DNS considerations

• Route DNS requests through the VPN to prevent leaks: configure VPN DNS settings to use a privacy-focused DNS provider within the VPN client options.
• If you experience DNS leaks, ensure the VPN client enforces DNS through the tunnel and disable fallback DNS on the device’s network settings.

Performance and testing tips

• Choose VPN servers geographically closer to your location for faster throughput.
• Run speed tests with VPN ON and OFF to gauge performance impact.
• Check for DNS leaks using tools like dnsleaktest.com while connected to VPN.
• Confirm your real IP is masked by checking whatismyipaddress.com or similar sites.
• Use a VPN provider with a solid no-logs policy and a good uptime track record.

Security best practices

• Keep your UniFi Dream Machine firmware up to date.
• Use strong, unique credentials for your VPN and the UniFi Controller.
• Prefer certificate-based authentication over password-based when possible.
• Enable automatic reconnect and keepalive settings to prevent dropped tunnels.
• Regularly rotate VPN credentials and monitor tunnel status for unusual activity.
• Consider enabling two-factor authentication for the UniFi Controller.

Common pitfalls and fixes

• VPN won’t connect: double-check server address, port, and protocol; ensure credentials are correct; verify that your WAN connection is active.
• VPN disconnects frequently: check keepalive settings and server load; try a different VPN server.
• DNS leaks: ensure DNS routing is enabled in VPN settings and that devices favor VPN DNS over local ISP DNS.
• Split tunneling misconfig: review which subnets are pushed through the VPN; test with and without split tunneling to verify traffic behavior.

Table: Quick comparison of VPN options on UDM

• IPSec
  • Pros: Broad compatibility, strong security
  • Cons: Complex setup, potential DNS routing quirks
• OpenVPN
  • Pros: Broad support, mature ecosystem
  • Cons: Slightly heavier on CPU, config-heavy
